T o all whom fit may concern: `V

Be it known that I, THOMASL. KENNEDY, a citizen of the United States,residing at.

Philadelphia, in the `countyof Philadelphia and State of Pennsylvania,have invented certain Vnew and useful ."Improvementsfin Gear-Cases, ofYwhich the following is a specification. V

Under the present -construction gear 11 cases as used upon tractionvehicles, the lug quently when these bolts break, it is neces` sary tosend the' car to y.therepair shopfand bore out the broken part ofthebolt remaining in the motor frame and gearcase,which obviously throwsthe" car out ofcomniission for some length of time and furtherfis atedious and expensive way of repairing the break. i y The principalobject -of the presentI invention is to overcome the abovedescribed"dis-1l advantageous features and toprovide means for securingthe parts of the gear case to a motor frame of simple construction,cheap of manufacture and efficient in use.

A further object of the present invention is to provide means wherebytheparts when broken may be expeditiously removed and new parts insertedwithout .sending'the car to the repair shops.

Other objects relate to details of constructifon as will be more fullydescribed hereina ter.

ments hereinafter described and, nally claimed.

The nature, characteristic features .and scope `of the invention will'be more fully understood from the following description taken inconnection with the accompanying drawings forming part hereof and inwhich:

Figure 1, is a top or plan view partly sectioned of so much of a truckof a traction vehicle as is necessary to the understanding of theinvention. Flg. 2, isV a central sectional view illustrating the gearcase Vof the invention. Fig. 3, is a view in plan of the same partlysectioned and Fig. 4, is a view in elevation of certain of the partsshown4 The invention consists vin the yim rove-v Referring to y ,thedrawings and more especially to Fig.' (1, there is illustrated a truckframe 1, shown asbeing equipped with traction wheels 2, mounted uponaxles 3. `Carried by the axles v3, is a gear wheel 4, that meshes with'a gear 5, mounted upon the shaft' ofthe motor 6. The motor 6, iscontained within a motor box 7 carried` by the frame 8, of the truck 1,in a well understood manner. Covering thegears 4, and 5, `is a two-partgear casing 9, shown as comprising a pair of generally hemisphericalysections 10, and 11, provided with flanges 12, `that abut and aresecured Vtogether by means of bolts As clearly illustrated in Fig. y2,these flanges 12,.are countersunk as at 14, `for the reception of thebolt heads and securing nuts, the bolt ends extending beyond fonefof theflangesV 1'2, and being equipped withcotterfpins 15. Such a constructionserves toprevent the securing nuts from `loosening by virtue ofthe jarsreferred to the gear casing. l l -The `se`ctionsf10,V and 11,0f thegearcasing are each provided with a hollow circular extension 16, thatproject beyond the gear case sections'and abut against one of the wallsof the motor frame 7, as clearly illustrated in Figs.` 1, and 2. Asshown the said hollow extensions 16, are horizontally slotted as at v17, as is -also 4the motor frame as at 18. Adapted for passage throughthe said slots 17, and18, byway of the motor box 7, is a `.generally T-shaped bolt 19, comprising a threaded shank 20, carrying a head 21. This"T-bolt when inserted is turned so that its head 21, is'arrangedcrosswise of the slot 17, and, abuts against a lug or stop 22, locatedwithin the'recessed portion 23, of the extensions 16, and a securing nut24, and a lock nut25, are screwed to place upon the threaded part 20, ofthe bolt 19, thus firmly clamping to place the gear casing with respectto the motor frame. A cotter pin 26, is then appliedV to the end of thebolt 19, to prevent the nuts 24, and 25, becoming loose during thejarring of the vehicle parts. By such a construction it will at once beapparent that should the bolt 19, become broken the parts may be readilyremoved and new ones inserted in a very few moments without thenecessity of the car going to the repair shops. As shown in Figs. 2, and8, the section 10, of the gear casing 9, is provided with a lubrieatingaperture 27, covering which is a slide titanes@ CITOSSWiSe i Y e Are(zessed portion and mIe-ansjcarried at the 29, of the `said section 10.Use may VW hat I claim is l.
